When many people think of motion-capture technology, they think of people wearing reflective markers and having their movements captured on camera for use in modeling figures created by animation or computer graphics. Motion capture is frequently associated with movies or videogames. Now, motion technology is moving in some new directions. Researchers are working on techniques that don't, for example, require placing hundreds of markers on models. Also, motion-capture applications are becoming less expensive and more readily available. Fields as diverse as medicine, manufacturing, and advertising are thus beginning to utilize the technology more often. Nonetheless, motion capture still faces challenges, such as output precision and ease of use.
